Thanks for your replies!!

hey Walter, Two straight question to u. 1. Can I get the same output as I have shown in the picture using MATLAB 2016b?

2. How can I learn Digital image processing?

The code I provided earlier with imagesc() appears to return that upper left picture. I do not have the data for the lower right pictures, and your two lower right pictures appear to be different original images

There are a number of books about digital image processing, which is a common university course. I do not have any to recommend myself, but the Gonzalez and Woods book is considered a classic; https://books.google.ca/books/about/Digital_Image_Processing.html?id=MaYuAAAAQBAJ&source=kp_cover&redir_esc=y
